We experienced "similar" results. In my 20 years of working with SAS
on MVS and OS/390, I'd say that each new version or release (SAS 79.5
thru 8.1) has:
* added functionality
* used more memory
* used more CPU
* run faster (from a "wallclock", not CPU, perspective)
I don't know that it's possible to "rectify" it. However, from time to
time you may find that new functionality presents an opportunity to
do things more efficiently; if you're willing and able to modify old code,
you may be able to get diminish the effects of SAS's larger footprint.

There are a few issues here and there, particularly if you still have some
Version 5 data and format libraries around.
